Recovery of RAID 5
Posted: Fri Dec 05, 2014 7:39 pm
Hi
I relied on R-Studio years ago to recover some crucial data from a single disk.
Recently however, my RAID 5 set up on am 8TB Terramaster F4-300 went offline with an error. The 'Terramaster HW Raid Manager' reported "[Controller 1: 1, Disk 1: ST3000DM001-1CH166 (W1F22KE9)] Error- This disk has the following error(s): Page 0 Damage Error"
Strangely, the HW Raid Manager reported Disk 1 W1F22KE9 as having the error, but the LED light on the unit itself indicated that the disk in the HDD2 slot was faulty. I turned the unit off, and found that the serial number on the disk in the HDD2 slot was W1F22KE9. I pulled the disk and replaced it with a new harddisk of identical brand and size, nothing happened. The Terramaster F4-300 unit did not try to rebuild the 8TB RAID array. After extensive searching online, I found that the Terramaster has a good reputation in China and the problem lay in the use of Seagate ST3000DM001 3TB disks which are now on the "not recommended" list of most NAS makers.
When I rebooted, Windows 8 "Disk Management" (inside "Computer Management") wanted to initialize the entire F4300 RAID. I did not do this. I shut the unit off and have been seeking advice on how to proceed.
What is the best way to proceed. I read the recovery guide here: community.spiceworks.com/how_to/show/24731-recovering-data-from-a-failed-raid-5-on-desktop-pcs
I am wondering what is the best way to make an image of the 5 disks from the Terramaster box.
Can I remove them and connect them to my notebook via BlacX Duet SATA dock (its USB or eSATA)?
Or must I connect them directly to the motherboard of a big desktop machine?
Do I scan the disks one by one?
Can I put the R-Studio scans on another NAS RAID box that can hold the 8TB?
Thank you very much for your recommendations. As soon as I understand the process, I'll get to work recovering the data.
Best Regards,
CA.
